Downgrade diagram signs
« on: June 22, 2009, 05:17:00 PM »

This one is on SB/EB US 322 between State College and US 22 in PA:


Turned up this one on WB I-90 at the ID-MT state line today:

Any others out there?

I found this one in 2000:



IIRC there is also another one on Idaho 55 north of Boise.

I believe there is one approaching Punxsutawney, PA from the south on US-119.

There's one on Alps's site, but I don't want to hotlink off his site.

There are at least two on US 95 in Idaho between the international boundary and the Idaho 55 junction.  The ones I remember are at Lewiston Hill and White Bird Hill.  The Idaho 55 one is at Horseshoe Bend Hill:

http://winklers-roads.fotopic.net/p16863482.html

Street View has a really bad picture of the Lewiston hill descent sign:

http://maps.google.com/maps?q=Lewiston,+Idaho&ie=UTF8&ll=46.461707,-117.014995&spn=0.001885,0.004828&t=h&z=18&layer=c&cbll=46.461701,-117.01487&panoid=MiRFDWrFYuKhUCgtXNSjEg&cbp=12,184.91,,2,5.97

Idaho is far from alone in using this kind of signing.  Wyoming has beautifully elaborate ones on US 14 ALT west of Burgess Junction, but they are unlikely to show up well on Street View because they are at truck laybys, set well back from the road--a problem which is very typical of hill descent signs in general.

Fortunately I do have pictures, because I always made a special point of stopping and photographing these hill descent treatments when I travelled in the Rocky Mountain states.

There are not too many of these signs on Interstates, though I-84 over Cabbage Hill in Oregon has special advisory signing for trucks and the no-services bit of Utah I-70 has a proper hill descent sign at the Spotted Wolf Alignment.

I have that one, and several others, in my Guide Signs gallery.

Idaho has one on 55 at the top of Horseshoe Bend Grade, and then there are some on US-95's Lewiston Grade, Midvale Grade and Whitebird Grade; Unfortunately I have pictures of none of those.

Here's Washington SR 272 west approaching US-195 and Colfax

Found our photo of the Idaho 55 sign mentioned by Jonathan above.



We also stopped for the guide sign at the Montana and Idaho state line for Interstate 90.

This page has pictures of signs (no diagrams though) on I-70 west of Denver.  Some of them seem like overkill, but I guess some people don't get the message easily.

Here's a diagram on NY 28 south of Mohawk from Upstate NY Roads.
